TECHNOLOGY FOR MANUFACTURE OF UNIVERSAL CLUTCHES FOR
PERFORMANCE, UNLOADED, WITHOUT FLANGE CONNECTION OF PIPE CUTTERS
IN HIGH PRESSURE PIPELINES
Kashcheev Vladimir Sergeevich
The technology of manufacturing a universal coupling for a non-welded, threadless, flanged connection of pipe sections in pipelines with a nominal operating pressure of 150 and more atmospheres. The implementation period is 1,5-3 months.
I have developed a technology for manufacturing universal couplings, made of various materials, for BREW welding of pipe sections (metal and plastic) of various diameters and purposes. This method of connection differs from the known technology of the firm " Georg Fisher " in that the pipe segments are fixed not by compressing the sealing material around the pipe, which does not provide strength of the connection at high pressure and when the pipes are positioned in a vertical plane, but by mechanically fixing the pipe segments in the coupling.
The strength of my joint is comparable to the strength of a single pipe with a nominal working pressure of up to 150 atm . In addition, the method of the proposed connection, carried out manually, eliminates significant physical effort during installation. The use of a new coupling eliminates the threading and welding of the flanges. The connection is made at different angles.
The value of the coupling lies in its ubiquitous application, but primarily in its use in difficult production conditions: in mines with gassed air and high explosive danger, in factories, etc.
